Hercules is on the road to the court of King Pelias of Iolcus to tutor Pelias' son Prince Iphitus in the use of arms. Pelias' beautiful daughter Princess Iole updates Hercules on the history of her father's rise to power and the theft of the kingdom's greatest treasure, the Golden Fleece. Some suspect—and it eventually proves true—that King Pelias has acquired the throne through fratricide. Hercules and Iole are attracted to each other and a romance eventually develops.
